Description

TECHNICAL FIELD

[0002] In the field of extra-high voltage direct current transmission, as a key power equipment, the installation quality and efficiency of circuit breakers directly affect the operation performance and system stability of the transmission network.

[0003] For a long time, the power industry has generally used traditional crane manual assembly method for circuit breaker installation operation. This traditional installation method has the following disadvantages in practical application: (1) insufficient installation precision. On the one hand, it completely relies on manual operation, which is prone to human error; on the other hand, the traditional crane is connected to the lifting point of the porcelain sleeve group (such as T-shaped shell) by a steel wire rope or a lifting belt, which is prone to cause the porcelain sleeve group to shake, resulting in poor positioning precision. In this way, it is easy to cause mechanical damage to the equipment, and according to statistics, the equipment damage rate caused by traditional installation is as high as 15%. (2) Low operation efficiency. The installation process involves multiple types of cooperation, and the average time for single installation is 4-6 hours, which seriously affects the project progress. (3) Large quality fluctuation. The installation effect completely depends on the experience level of workers, and the quality is uneven, which increases the maintenance cost by more than 30%.

[0088] Regarding the second structure, when the fourth driving part 236 drives the adjusting screw 234 to rotate, the sliding seat 235 (and the profiling tool 30 on the sliding seat 235) can move in a straight line along the axis direction of the adjusting screw 234 (i.e. the direction of the guide rail 232), so as to realize fine adjustment.

[0089] That is, the first structure is used to receive the output of the coarse adjustment mechanism, and a near-parallelogram linkage and a balance oil cylinder 227 are used to provide stable transition and possibly provide a small attitude adjustment (such as fine adjustment of the levelness, small angle rotation) to prepare for the final high-precision slide positioning. It itself also has a certain fine adjustment capability, but the range is relatively small. The second structure can receive positioning from the first structure, and then can drive the entire profiling tool 30 to perform high-precision, quantifiable (the displacement can be calculated by the pitch of the screw) linear fine adjustment in one direction (which can be the vertical direction or the horizontal direction, etc.). In this way, the final positioning and alignment of more than one millimeter can be achieved.

[0090] Optionally, in order to prevent mutual interference between the components during movement, the rotation angle range of the first rotating disc 211, the second rotating disc 224, and the third rotating disc 226 can be 0°-350°.

[0091] As an embodiment, as shown in Figures 1 to 2 As an embodiment, as shown in

[0092] In the backward-tilting state, the third swing arm 221, the second rotating shaft 222, the fourth swing arm 223, the third rotating shaft 228, and the second rotating member 2292 can jointly constitute a first parallelogram linkage (an unclosed structure). The backward-tilting state refers to the direction of the entire second position adjustment assembly 22 relative to the third swing arm 221, so that the load (the profiling tool 30) is tilted upward and backward. In this posture, some linkages can be close to collinear or not fully form a closed loop.

[0093] In the forward-tilting state, the third rocker arm 221, the second rotating shaft 222, the fourth rocker arm 223, the third rotating shaft 228, the second rotating component 2292, the fourth rotating shaft 229, and the first rotating component 2291 can collectively form a second parallelogram linkage mechanism (closed structure), sharing the third rocker arm 221 and part of the connecting shaft with the first parallelogram. The forward-tilting state refers to the load tilting forward and downward. In this state, all links are tensioned or pushed, collectively forming a complete, closed force loop.

[0094] In other words, the second position adjustment component 22 can automatically or through control switch its main force mode and stabilization mechanism according to different working postures (tilt backward / forward). It may operate in an open mode during large-range movements, and enter a closed high-rigidity mode during fine-tuning and positioning, which is beneficial to improving the adaptability of the installation device.

[0095] As one implementation method, such as Figures 1 to 2 As shown, the second rotating member 2292 includes a first segment 22921 and a second segment 22922 connected together. The end of the first segment 22921 away from the second segment 22922 is connected to the bottom of the second turntable 224. A first connecting hole is formed on the end of the second segment 22922 near the first segment 22921, and a second connecting hole is formed on the end of the second segment 22922 away from the first segment 22921. The second segment 22922 is rotatably connected to a third rotating shaft 228 through the first connecting hole, and rotatably connected to a fourth rotating shaft 229 through the second connecting hole. The first segment 22921 and the second segment 22922 are set at an obtuse angle.

[0096] The obtuse angle design is the core of the entire linkage mechanism, enabling it to flexibly switch working modes, achieve precise alignment, and avoid interference.

[0097] First, it enables spatial misalignment and multi-point connections. Specifically, the third rotating shaft 228 and the fourth rotating shaft 229 are two parallel axes in space, but separated by a certain distance. If the second rotating component 2292 were straight or bent at an acute angle, it would be difficult to simultaneously connect two holes (the first connecting hole and the second connecting hole) on a single component to these two separate axes while ensuring a smooth, stress-free connection. The obtuse-angled bend of the second segment 22922 provides a spatial transition, allowing the first and second connecting holes to align naturally and without distortion, connecting to the third rotating shaft 228 and the fourth rotating shaft 229 respectively. This solves the spatial layout problem.

[0098] Second, the force transmission path can be optimized and stress can be reduced. Specifically, the obtuse angle design can optimize the force transmission direction. The forces from the third and fourth rotating shafts 228 and 229, when converging to the first segment 22921 through the second rotating part 2292, have a combined force direction closer to the axis of the first segment 22921, thereby reducing the bending stress inside the second rotating part 2292 and improving the strength and durability of the structure.

[0099] Third, motion interference can be avoided. Specifically, during the movement of the mechanism, the various connecting rods will rotate relative to each other. The obtuse angle bend of the second segment 22922 can better avoid some nearby components (such as the arm segment 2231, the first rotating part 2291, the cylinder body of the balance oil cylinder 227, etc.), preventing collisions or jamming during movement and ensuring the flexibility of the mechanism.

[0100] As an embodiment, as shown in Figures 1 to 2 The first position adjusting assembly 21 includes a first driving part 216, the second position adjusting assembly 22 further includes a second driving part 237 and a third driving part 238, and the first turntable 211 has a vertical rotation axis 334 line. The first driving part is in transmission connection with the first turntable 211 to drive the first rocker arm 212 to rotate relative to the vehicle body 10 around the rotation axis 334 line and change the azimuth angle with the vehicle body 10. The second driving part is in transmission connection with the second turntable 224 to drive the fifth rocker arm 225 to rotate relative to the fourth rocker arm 223 around the rotation axis 334 line of the second turntable 224 and change the azimuth angle with the fourth rocker arm 223. The third driving part is in transmission connection with the third turntable 226 to drive the profiling tool 30 to rotate relative to the fifth rocker arm 225 around the rotation axis 334 line of the third turntable 226 and change the azimuth angle with the fifth rocker arm 225.

[0101] Among them, the first position adjusting assembly 21 can provide 3 degrees of freedom. Specifically, the horizontal rotation (around the vertical axis of the first turntable 211) driven by the first driving part 216. The pitch (change the included angle of the first and second rocker arms 214) driven by the amplitude cylinder 215. The length adjustment (translation) caused by the extension and retraction of the second rocker arm 214.

[0102] Among them, the second position adjusting assembly 22 can provide at least 3 degrees of freedom. Specifically, the rotation of the fifth rocker arm 225 relative to the frame (around the axis of the second turntable 224) driven by the second driving part 237. The rotation of the profiling tool 30 relative to the fifth rocker arm 225 (around the axis of the third turntable 226) driven by the third driving part 238. The precise linear movement (translation) of the profiling tool 30 along the guide rail 232 driven by the fourth driving part 236.

[0103] In other words, through the position adjustment mechanism 20, the installation device of this disclosure can achieve fine adjustment of the contour tooling 30 with multiple degrees of freedom (at least 6 independent controllable degrees of freedom).

[0104] As one implementation method, such as Figures 1 to 4 As shown, the contouring fixture 30 includes a housing 31, a mounting bracket 32, and a limiting mechanism 33. One end of the housing 31 is connected to the second position adjustment assembly 22 (specifically, the slider 239 and the sliding seat 235), and the other end of the housing 31 is connected to the mounting bracket 32. The limiting mechanism 33 is installed on the housing 31 and is used to limit the parallel capacitor. The mounting bracket 32 ​​is used to fix the T-shaped body of the arc-extinguishing chamber porcelain sleeve.

[0105] The housing 31 provides support and a safe distance to prevent interference between the ceramic sleeve assembly and the second position adjustment component 22. Specifically, when the entire device undergoes complex multi-degree-of-freedom adjustments (such as horizontal rotation, pitch, extension, etc.), the housing 31, as an intermediate connector, effectively isolates the ceramic sleeve assembly from direct contact with the second position adjustment component 22, preventing accidental collisions or friction caused by mechanical movement.

[0106] The mounting bracket 32 ​​is used to secure the T-shaped housing of the arc-extinguishing chamber porcelain bushing. This prevents unnecessary shaking of the T-shaped housing and the connected arc-extinguishing chamber porcelain bushing body during transportation and installation.

[0107] The limiting mechanism 33 can limit the parallel capacitor, preventing it from shaking or rotating due to gravity during transportation and installation, which would cause the porcelain bushing of the arc-extinguishing chamber to shake or rotate as well.

[0108] As one implementation method, such as Figures 2 to 4As shown, the mounting rack 32 comprises a mounting rack body 321 and a cover plate 322, and the limiting mechanism 33 comprises a cylinder 331, a fifth driving member 332, a transmission assembly 333, a rotating shaft 334 and two limiting members 335. The mounting rack body 321 comprises a side plate 3211 and a plurality of support columns 3212 surrounding the side plate 3211. The ends of the plurality of support columns 3212 away from the side plate 3211 jointly define a taking and placing opening 3213. The cover plate 322 is detachably connected to the taking and placing opening 3213. The taking and placing opening 3213 is configured to allow the T-shaped casing member to pass through when the cover plate 322 is removed from the mounting rack body 321. The shell 31 has an accommodation cavity 311. The cylinder 331 is arranged in the accommodation cavity 311. The cylinder 331 comprises a cylinder body 3311 and a mounting portion 3312 protruding from the cylinder body 3311. The cylinder body 3311 penetrates the shell 31. The inside of the cylinder body 3311 forms a channel 3313. Both ends of the channel 3313 are configured as open ends. Each open end is flush with the side wall of the shell 31. An installation cavity 3314 is formed in the mounting portion 3312. The installation cavity 3314 is in communication with the channel 3313. Both ends of the rotating shaft 334 are rotatably connected to the cavity walls of the installation cavity 3314. Each limiting member 335 is configured as a limiting cylinder structure. Both limiting members 335 are located in the channel 3313 and are movably connected to the rotating shaft 334. The fifth driving member 332 is located outside the installation cavity 3314. The output shaft of the fifth driving member 332 is in transmission connection with the first rotating shaft 213 through the transmission assembly 333. The first rotating shaft 213 can drive the two limiting members 335 to move closer to or farther away from each other, so as to switch the two limiting members 335 between the working state and the closed state. In the closed state, the two limiting members 335 are close to each other. Both limiting members 335 are retracted into the channel 3313, and the end of each limiting member 335 away from the other limiting member 335 is flush with the corresponding open end. In the working state, the two limiting members 335 are away from each other. Part of each limiting member 335 extends out of the channel 3313 to be in plug-in connection with the parallel capacitor.

[0109] The mounting rack 32 adopts the design of frame + detachable cover plate 322, which can realize convenient mounting and dismounting (through the taking and placing opening 3213) and reliable fixing and protection (after the cover plate 322 is closed) of the arc-extinguishing chamber porcelain sleeve (T-shaped casing).

[0110] Alternatively, the two parallel capacitors can be installed on the arc-extinguishing chamber porcelain sleeve in the same direction or in different directions.

[0111] For the embodiment that two parallel capacitors are installed in the same direction on the porcelain sleeve of the arc-extinguishing chamber, specifically, the parallel capacitors of the porcelain sleeve group can be placed towards the direction of the shell 31, and then the cover plate 322 is detached from the mounting rack body 321, and then the porcelain sleeve (T-shaped shell) of the arc-extinguishing chamber of the porcelain sleeve group can be moved to the inside of the mounting rack 32 through the taking and placing opening 3213. At this time, the horizontal part of the T-shaped shell is lapped on both ends of the two support columns 3212 located at the bottom, and the vertical part of the T-shaped shell passes through the gap between the two support columns 3212 located at the bottom, so as to be connected with the top connection position of the support column. Finally, the cover plate 322 is arranged on the taking and placing opening 3213 through the fixing bolt cover. The shape of the support column 3212 can be set to be matched with the T-shaped shell.

[0112] After the preliminary fixation of the porcelain sleeve group is completed, the parallel capacitors at this time are aligned with the limiting cylinders. The fifth driving member 332 can be started to drive the rotating shaft 334 to rotate through the transmission assembly 333, and the rotation of the rotating shaft 334 can make the two limiting members 335 move towards each other in the direction away from each other, at this time, part of the limiting cylinder structure of the two limiting members 335 extends out of the channel 3313 and protrudes from the side wall of the shell 31. The extended limiting cylinder structure and the corresponding parallel capacitor can realize plug-in cooperation, which can effectively prevent the parallel capacitor from shaking or rotating due to gravity, inertia or external disturbance, thereby avoiding unnecessary movement of the arc-extinguishing chamber porcelain sleeve.

[0113] When the limiting mechanism 33 is in the closed state, the fifth driving member 332 can be started to drive the rotating shaft 334 to rotate through the transmission assembly 333, and the rotation of the rotating shaft 334 can make the two limiting members 335 move towards each other in the direction away from each other, and the two limiting members 335 can be completely retracted in the channel 3313, and the end of each limiting member 335 can be flush with the side wall of the shell 31. At this time, the limiting mechanism 33 does not protrude outside the shell 31, forming a flat surface. In this way, it can avoid the interference or hooking of the limiting member 335 with the surrounding objects or parts during the operation process of the entire device in the idle state (i.e. non-working state, the profiling tool 30 is not provided with the porcelain sleeve group), and can ensure the safety and smoothness of the operation.

[0114] As an embodiment of the transmission assembly 333, as shown in Figure 4As shown, the axis direction of the output shaft of the fifth driving member 332 is arranged at an angle with the axis direction of the rotating shaft 334, the transmission assembly 333 comprises a transmission rod 3331, a driving bevel gear 3332 and a driven bevel gear 3333, the rotating shaft 334 comprises a positive helical section, an intermediate section and a reverse helical section, the positive helical section and the reverse helical section are respectively connected to two ends of the intermediate section and respectively extend in directions away from each other, the bottom of one of the two limiters 335 is provided with a first sliding block 336, the first sliding block 336 is formed with a first threaded hole, and the first sliding block 336 is threadedly connected to the positive helical section through the first threaded hole, the bottom of the other of the two limiters 335 is provided with a second sliding block 337, the second sliding block 337 is formed with a second threaded hole, and the second sliding block 337 is threadedly connected to the reverse helical section through the second threaded hole, the driving bevel gear 3332 and the driven bevel gear 3333 are arranged in the mounting cavity 3314, one end of the transmission rod 3331 is connected with the output shaft of the fifth driving member 332, the other end of the transmission rod 3331 is sleeved with the driving bevel gear 3332, the driven bevel gear 3333 is sleeved on the intermediate section, the driving bevel gear 3332 and the driven bevel gear 3333 are in mesh with each other, the mounting portion 3312 is formed with a through hole communicating the mounting cavity 3314 and the containing cavity 311, the fifth driving member 332 is contained in the containing cavity 311, and the output shaft of the fifth driving member 332 or the transmission rod 3331 penetrates through the through hole.

[0115] As an implementation form, as shown in Figure 1 and Figure 2 As shown, the image acquisition assembly comprises a camera 40, and the camera 40 is installed on the profiling tool 30 and used for shooting the power equipment in the monitoring area, wherein the monitoring area is arranged as a space vertically above the vehicle body 10, and the mounting device further comprises a control system and a human-computer interaction interface, the control system is electrically connected with the human-computer interaction interface, the position adjusting mechanism 20 and the profiling tool 30, and the control system is integrated with a power module, an image acquisition and identification module and a communication module.

[0116] The camera 40 can be installed on the second position adjusting assembly 22 or the profiling tool 30 and used for shooting the power equipment in the space vertically above the vehicle body 10. In this way, real-time images of the power equipment and the surrounding environment thereof can be provided to help the operator visually confirm. In addition, during the installation process, the camera 40 can capture detailed images of the target position (such as the top end of the support column), and combined with image recognition technology, more accurate positioning can be realized. The camera 40 can also record key pictures in the entire installation process, which is convenient for subsequent analysis and troubleshooting.

[0117] Specifically, the camera 40 captures images of the power equipment located in the space vertically above the vehicle body 10 in real time and transmits the images to the image acquisition and recognition module in the control system for processing. Based on the image analysis results, the control system automatically adjusts the positions of the position adjusting mechanism 20 and the profiling tool 30, so that the porcelain sleeve set is accurately aligned with the predetermined position above the circuit breaker support. After ensuring that the porcelain sleeve set has been aligned with the target position, the position adjusting mechanism 20 smoothly transports the porcelain sleeve set directly above the circuit breaker support to ensure that the porcelain sleeve set is completely in place, ready for the subsequent manual installation.

[0118] Through the set human-computer interaction interface, on the one hand, the control system can display the real-time picture taken by the camera 40 on the display screen in front of the staff.

[0119] On the other hand, the control system can also superimpose key information on the real-time video picture, for example, mark the ideal position of the support connection point and the porcelain sleeve set docking end recognized by the system. Use arrows, distance values, angle values, etc. to intuitively display the current alignment deviation. Display the current state of the system (such as "automatic positioning", "already in place, ready for installation", "system failure", etc.). Visualize the complex machine recognition results, making it easy for the staff to quickly understand the system's intentions and current situation, facilitating monitoring and decision-making.

[0120] In addition, the staff can directly send instructions to the control system through the control panel or remote control of the human-computer interaction interface to manually control the degrees of freedom of the position adjusting mechanism 20. The staff can also set or modify system parameters on the interaction interface.

[0121] In addition, the human-computer interaction interface can also realize interaction in the collaborative work process. Specifically, when the system automatically completes the positioning, it will prompt "accurately in place, ready for manual installation" through the interface. This can clearly indicate the end of the automation stage and the beginning of the manual stage, thereby avoiding misoperation.

[0126] Step four: the interface at the top of the support is captured by the image acquisition assembly, the control system identifies the relative deviation between the connecting flange of the arc extinguishing chamber porcelain sleeve and the support interface, and according to the prompt of the man-machine interface, the second position adjusting assembly 22 is controlled to finely adjust the position of the profile tool 30 until the connecting flange of the arc extinguishing chamber porcelain sleeve is accurately aligned with the support interface;

[0127] Step five: the staff member is lifted to the position beside the support interface by the lifting platform to complete the installation of the arc extinguishing chamber porcelain sleeve and the shunt capacitor with the support;

[0128] Step six: after the installation is completed, the cover plate 322 is detached from the mounting frame 32, the fifth driving member 332 is started to drive the two limiters 335 to retract into the cylinder body 331, the profile tool 30 is moved away and reset by the position adjusting mechanism 20, and the next operation is prepared.
